This example demonstrates a simple gantt chart.<br><br>
This chart is created by using a horizontal box-whisker layer, in which only the "box" part of the box-whisker layer is used. Date/time values are used as box data, resulting in a gantt chart.<br><br>
The key features demonstrated in this example are:<br><br>
<ul><li> Create the box-whisker layer using <a href="XYChart.addBoxWhiskerLayer.htm">XYChart.addBoxWhiskerLayer</a>, in which the data arrays are dates.<br><br>
<li> Swap the x-axis and y-axis using <a href="XYChart.swapXY.htm">XYChart.swapXY</a>, so the chart is using a horizontal orientation.<br><br>
<li> Use <a href="XYChart.setYAxisOnRight.htm">XYChart.setYAxisOnRight</a> to move the y-axis to the opposite side of the plot area, so that the y-axis is at the top of the plot area. (<b>Note:</b> the "right" word on setYAxisOnRight means the "right" side before "swapXY" rotation. After rotation, the right side will become to top side.)<br><br>
<li> Use <a href="Axis.setReverse.htm">Axis.setReverse</a> to reverse the direction of the x-axis, so that the x-axis is vertical from top to bottom (instead of from bottom to top).<br><br>
<li> Set the y-axis to date scale using <a href="Axis.setDateScale.htm">Axis.setDateScale</a>.<br><br>
<li> Set multi-format axis labels for the y-axis using <a href="Axis.setMultiFormat.htm">Axis.setMultiFormat</a>. Note that the labels for the first week of the month are in bold, with the month name shown. The other labels just show the day.<br><br>
<li> Use alternative background colors for the plot area by providing two background colors when calling <a href="XYChart.setPlotArea.htm">XYChart.setPlotArea</a>.</ul>
